Operating instructions
56
To minimise risks caused by limited visibility, rules and procedures
shall be established by the management on the work site. For
example:
Q Make sure that operators and others working on the site have
received adequate safety instructions.
Q Control the traffic flow of machines and other vehicles. If
possible, avoid reversing.
Q Limit the machine's operating area.
Q Use a signal man to help the operator.
Q Make available equipment for two-way communication as
needed.
Q Make sure that workers on the site communicate with the
operator before approaching the machine.
Q Use warning signs.
The standard ISO 5006 "Earthmoving machinery – Operator's field
of view" covers the operator's visibility around the machine and is
intended to be used when measuring and evaluating visibility and
field of view. Conforming to this standard is a requirement in EU-
countries, and gives improved visibility around the machine.
The machine is tested according to methods and criteria for this
standard. The method used to evaluate visibility cannot cover all
aspects of the operator's field of view, but it gives information to
determine if optional equipment/extra devices are needed for
indirect visibility, such as warning systems.
The test was conducted on machines with standard equipment
and standard attachments. If the machine is modified or equipped
with other equipment or attachments, resulting in reduced visibility,
it shall be tested again according to ISO 5006.
If other equipment or attachments are used and visibility has been
reduced, the operator must be informed.
Measures before and during operation
Q Walk around the machine and check that there are no
obstacles next to the machine.
Q Check that mirrors and other visibility-enhancing devices are in
good condition, clean, and correctly adjusted.
Q Check and make sure that the horn, back-up warning signal,
and the rotating beacon (optional equipment) work as intended.
Q Check if the management has established rules and
procedures for the work site.
Q Always pay attention around the machine to identify any
obstacles.

The machines are equipped with a mirror which,
when correctly adjusted, gives improved
visibility in front of the machine.
